A typical DDR memory system needs at least two main power supplies: VDD for the I/O power and VTT for the termination power. To ensure good signal quality and fast data rate, the termination power supply (VTT) must always track the VDD with VTT=VDD/2. 6V. Since the termination resistors can carry current in either direction, the VTT power supply must be able to both source and sink current while tracking the VDD supply. A family of new termination/tracking controllers, including the LTC3717, LTC3718 and LTC3831, satisfy these DDR requirements.
The LTC1695 shuts down its PMOS pass transistor and sets the THE bit high if die junction 18 Conclusion The LTC1695 improves battery run times and reduces acoustic noise in portable equipment. In addition, it provides important performance and protection features by controlling the operation of the equipment’s cooling fan. It comes in a SOT-23 package and is easily programmed via the SMBus interface. Active voltage positioning reduces output capacitors 8 Robert Sheehan Introduction Power supply performance, especially transient response, is key to meeting today’s demands for low voltage, high current microprocessor power.
The LED current smoothly ramps up and down at one of four different rates. Overvoltage protection prevents the internal power transistor from damage if an open circuit fault occurs. 75W at 36V. Many circuits require a dual polarity voltage to bias op amps or other analog devices. 2, can be added to the boost converter switch node to provide a dual polarity supply. Two forward diodes are used to account for the two diode voltage drops in the inverting charge pump circuit and provide the best cross-regulation.
